Voltage measurement (U)
Voltage measurement is possible on all 5 inputs. The voltage to be measured is connected between
an input terminal for voltage (see connection diagram) and a ground terminal.
)
Note
The signal must not be carrying external potential!
The measurements 0(2)...10 V are selected by the software.
The maximum voltage without damage is < 50 V, but the displayed range is limited to 10 V and the
internal resistance Ri of the input is > 20 kΩ.
Current measurement (I)
With external resistance connected in parallel to the voltage input, current measurement is possible
on all 5 inputs.
)
Note
The signal must not be carrying external potential!
Potentiometer measurement
Potentiometers are connected to the U, ground and +5 V terminals.
To avoid overloading the reference output, the potentiometer value should be at least 1 kΩ. Potentiometers can be used on all 5 inputs.
Note: If required, the analogue inputs can also be used as digital inputs. This means that the 13 V
power supply (terminal 16) is input as a reference via external contacts and is connected to the analogue inputs.
The software uses the limit values to detect:
• Voltage present = 1
• No voltage present = 0
Thus, the BI soft module can be used to display and evaluate an analogue input digitally.

Potential-free contacts, opto-couplers or open-collector transistors can be connected to the meter inputs. The maximum pulse frequency may be up to 15 Hz. To ensure that switching contacts are recorded correctly, a de-bounce time of 20 ms is used. The pulse is recorded on the falling edge and may
be present for an unspecified length of time.
The internal counter value of the station is queried in every cycle, and the totalling to the actual counter value is performed in the software after 30 seconds at the latest by the processor of the station.
The format enables counter values up to 67,108,864 to be represented with a resolution of 1.

8 digital inputs can be connected directly to the universal controller. Digital inputs are connected between the input and ground terminals. The bit is 0 for an open contact and 1 for a closed contact. The
station applies a voltage of 13 V to the terminal, and a current of approximately 0.4 mA flows when
the contact is closed. Short-term changes of at least 30 ms between the station queries are stored
temporarily and processed during the next cycle.
For every digital input, setting software parameters can be used to select individually whether it is
used as an alarm or a status value.
Note: By assigning the corresponding MFAs (50/51), the two digital inputs at terminals nos. 39 and 40
can also be used as pulse counters.

Note
The outputs are not protected against external voltage!
Clock and battery concept
A Real Time Clock (RTC) is integrated into the universal controller for the time programmes, and the
date and time are set in the factory. A lithium battery ensures that, if there is a power failure, the user
data (CASE Engine data), parameterised time programmes and historical data (HDB) are retained in
the SRAM. The battery enables the data to be retained and the Real Time Clock to be operated without a power supply for at least 3 years from the production date of the controller. When the power
returns, the universal controller will check the consistency of the data and start the communication.
It is recommended to store the user data in a user PROM, as this strengthens the security against
data loss. The user PROM can be programmed using a commercially available device and then be
inserted directly into the station.
User program
The universal controller contains a fast operating program. It reads in all inputs, processes the parameterised modules, updates the outputs and handles the necessary communication with other automation stations and visualisation PCs via novaNet (only with auxiliary module 0374413 001).
The universal controller contains a total of 128 machine fine addresses (MFA) for the parameterisation with CASE Engine. In general, MFAs 0…59 are used for the HW addressing and MFAs 64…127
for the SW addressing. MFAs 60…63 are reserved service addresses and are for internal usage.
All user programs can be read in/out from any novaNet connection when using the auxiliary module.
Additionally, the data can be stored in a non-volatile user memory (User PROM). This ensures a very
high degree of security with regard to data loss.
Memory structure
The universal controller has RAM totalling 3 Mbits, divided into 3 sections of 1 Mbit each. The RAM,
the microprogramme memory and the HDB memory. Each of these areas is divided into 128 machine
fine addresses (MFA) of 128 double words (DW) of 32 bits each.
The RAM is used to process the loaded application data via CASE Engine and can be parameterised
(reading and writing). During the initialisation of the universal controller, the stored user data is loaded
automatically from the User PROM (if this exists).

Product data sheet
The microprogramme RAM is reserved for the internal use of the current microprogramme and cannot
be overwritten.
The HDB memory (historical data base) is used to save and reproduce digital and analogue values. A
historical entry of an MFA is parameterised in CASE Engine and requires a total of 72 bits. It is possible to save a total of 3584 historical entries in a universal controller (ring memory).
This is divided into 2 blocks of 1792 entries each.
Block 1:
1792 pieces of digital information in MFAs 0-127
Block 2:
1792 pieces of analogue information in MFAs 0-127
Time programmes and calendars
The universal controller has a special area within the RAM that can hold a total of 320 time commands. The parameterisation of the schedules is performed via the management software or the
manual operating unit.
On the level above the individual time programmes there is a yearly table that can be configured for 2
years (even/odd year number).
Summer- and wintertime
The automatic changeover for summer- and wintertime is a part of the universal controller and can be
changed or deactivated using parameterising software or a manual operating unit. The factory setting
is for the changeover for summer- and wintertime to be on the last weekend of March and October
respectively, from Saturday to Sunday.
Manual operating units
The modu240 (EY-OP240F001) operating panel is available as an accessory for the universal controller. It is connected directly via the RJ-45 socket. The operating panel enables data from the universal
controller (with the exception of the HDB) to be processed, e.g. reading measured values, alarms and
status, changing setpoints, outputting positioning commands and changing schedules.
The modu250 touch-panel can also be used as an additional accessory. For direct connection, you
use the point-to-point module (accessory 0374448 001) with integrated RJ-11 socket, limiting the cable length to max. 6 m.
Starting up the universal controller
When the power supply is being connected, the protective earth absolutely must be connected with
the terminal screw provided (protection class I). The work must always be carried out when the system is disconnected from the electrical supply.
The universal controller has an indicator (green LED) for the operating voltage which lights up continuously to indicate the “ON” operating status.
novaNet auxiliary module (optional)
If the universal controller is to be connected to a novaNet network (e.g. for parameterisation), this is
only possible when using the auxiliary module. Here every controller must be given a unique address
between 0 and 128. The address is binary coded manually on the auxiliary module via the 8 DIP
switches.
B09611 A yellow LED on the novaNet auxiliary module flashes to indicate the “Send” telegram traffic.
Example of a setting: AS number 15
1 + 2 + 4 + 8 = 15 (Even Parity: OFF)
The parity switch is set so that the number of switches set to “ON”, including the parity switch, is an
even number.
In principle, the user data is read in via CASE Engine. The communication is performed via the novaNet SAUTER system bus at terminals a and b, and the novaNet auxiliary module must be used. The
programming can be performed in parallel with the ongoing data traffic.
So as not to reduce the communication speed of other novaNet subscribers, the station can be disconnected from the novaNet for the programming period and the parameterising PC connected locally. After the data transfer, the data is active immediately.
Initialisation
The initialisation is performed by short-circuiting the two “Ini” half-moon buttons (under the housing
cover) for 1-2 seconds. The effect of this is that the universal controller deletes the entire RAM and
